INSTALLATION
general
The following items must be considered prior to
pump installation:
1. LOCATION - locate the pump as close as
possible to the supply of liquid being pumped.
If possible locate the pump below liquid supply.
Viking pumps are self-priming; but, the better
the suction conditions, the better the pump will
perform.
2. ACCESSIBILITY - the pump must be accessible
for inspection, maintenance and repair.
3. SUCTION/DISCHARGE - the RP series pumps are designed for clockwise rotation as
standard (viewed from end of shaft). Refer to Figure 2.
Mounting
1. Surfaces to which the pump mounts must be clean and flat.
2. Use SAE Grade 5 or better capscrews to mount pump.
3. The mounting capscrews for RP-07 pumps must have a minimum of ½ inch thread
engagement.
4. RP series pumps with mechanical seal or lip seals are designed to be used with jaw type
couplings that do not induce axial thrust on the pump shaft. If an improper type coupling is
used, internal damage may result.
5. Do not strike or press the coupling half to install on the pump shaft. Damage to the pump or
coupling may result. If the coupling does not slide onto pump shaft, inspect coupling bore,
shaft and key for nicks or burrs and remove if present.
6. Once pump has been mounted, place a small amount of compatible liquid into suction port
and turn by hand to ensure pump turns freely.
Alignment
Check alignment after mounting.
1. If the unit has a flexible coupling, remove
any coupling guards or covers and check the
alignment of the coupling halves. A straight
edge (piece of key stock will work) across
coupling must rest evenly on both rims at top,
bottom and sides. See Figure 3.
2. Make final check on alignment after piping is
hooked up. Replace the guards.

USE STRAIGHT EDGE. THESE
SURFACES MUST
BE PARALLEL
CHECK WIDTH BETWEEN THESE SURFACES WITH INSIDE CALIPERS OR FEELER
GAUGE TO BE CERTAIN THE FACES ARE EQUAL DISTANCE APART AND PARALLEL.
